Apparatus and associated methods relate to an autonomous controllable valve system for providing turbulent flow to a cleaning solution during a valve-cleaning operation, the valve system includes a valve and a valve controller, the valve has an MR sensor array arranged to receive a magnetic field from a magnet coupled to the valve stem, the MR sensor array generating signals indicative of a valve stem position, the valve controller receiving the position signals and generating a control signal for a valve actuator to move the valve stem to a cleaning position between a closed position and a maximal-open position. The cleaning position may be less than twenty percent of a distance between the closed position and the maximal open position. In an illustrative embodiment, the cleaning position may be predetermined to cause a turbulent flow of the cleaning solution.
